<p><strong>黄道十二宫杀手</strong>（Zodiac Killer）可能是世界上最知名的高智商连环杀手，52年来从未被抓获。这个连环变态杀手，在美国加州南部杀死了至少5人，声称自己手上有<strong>37条人命</strong>。作案的同时，他寄送了很多封以<strong>挑衅</strong>为主的信件给媒体，这些信件中包含着一些未公开的细节以及犯罪证据，甚至在其中署名。虽然一封408字符的文件已经被专家破解，但是其他信件继续困扰了警方和密码学专家<strong>51年</strong>。</p>
<p>1969年11月8日，在杀死了两名受害者之后，他向《旧金山纪事报》致信，并随信附上了340个加密字符。该密码被称为<strong>Z-340</strong>，或简称为340，一直未曾有人成功破解。</p>
